Hi there,
This code gives me wrong output. I don't know why!
event message_t* Receive.receive(message_t *msg, void *payload, uint8_t
len) {
int32_t p = getRssi(msg);
// t1 = p - c, where c = -67.03
int32_t t1 = p + 67.03;
// t2 = t1 / a, where a = -15.73
int32_t t2 = t1 / -15.73;
// d = 10^t2, where d is the distance in meters.
int32_t d = powf( 10.0, t2 );
printf("%d dBm , %d m\n", p , d);
//printf("Rssi Message received from node %d: %d dBm\n", call
Ieee154Packet.source(msg), getRssi(msg));
printfflush();
return msg;
}
I cannot add/div float numbers, and I cannot print float numbers in printf
!!
I'm using iris mote and tinyos, nc.
Cheers,
